The VEX Accelerometer measures accelerations on three axis simultaneously. By measuring the acceleration of the robot, one can calculate the velocity of the robot, and more importantly the distance this robot has travelled. Accelerometers are also great for detecting collisions and determining if the robot is stopped or moving.

The LIS344ALH capacitive micromachined accelerometer features signal conditioning, a 1-pole low pass filter, temperature compensation and g Select which allows for the selection among 2 sensitivities. Zero-g offset full scale span and filter cut-off are factory set and require no external devices.
